Why choose pressure welding for connector termination?

Termination refers to how the contact pairs of a connector are connected to a wire or cable. Reasonable selection of termination methods and correct use of termination technology is an important aspect to improve the use effect of connectors.

Common termination methods include welding, crimping, wrapping, piercing, and screwing.

Among them, crimping, also known as pressure welding, is a technique that compresses and displaces metal within specified limits and connects wires to contact pairs, implementing the IEC 60352-5 standard. A good crimp connection can produce metal mutual flow, which causes the wire and contact to deform symmetrically to the material. This type of connection is similar to a cold-welded connection, which provides better mechanical strength and electrical continuity and withstands harsher environmental conditions. It is generally believed that the correct crimp connection is more stable and reliable than the soldering process, especially in high current applications, the crimping process performs better. Although the effect of pressure welding termination is outstanding, the final choice of termination method for different products depends on the specific needs of customers.
